Kyparissoudas, D.S. 1987a Flight of San José scale Quadraspidiotus perniciosus males and time of crawler appearance in orchards of northern Greece.. Entomologia Hellenica 5(2): 75-80.

Notes: The seasonal flight of Q. perniciosus, males was studied during 1984-87 in peach and nectarine orchards, under two different climatic conditions in central Macedonia (northern Greece), using sex pheromone traps. In late-season regions there were three periods of male flight activity, while in early-season regions there was also a partial fourth one. Pheromone traps and sticky-tape traps can be used for the study of phenology of San José scale, under conditions prevailing in northern Greece.
